Samsung has announced the long-rumored Gear S2 smart watch Monday, which comes with an impressive rotating bezel and runs on Samsung’s own Tizen operating system. There are two variants of the wearable -- Gear S2 and Gear S2 Classic -- that will be launched at the IFA 2015 event on Sept. 3.

Speaking of color choices, the original Samsung Gear S2 will reportedly be made available in dark gray case with black silicon band. The other choice is the silver case with white silicon band. On the other hand, the classic variant will apparently come with a black case and a matching genuine leather band. The devices feature a minimalistic look with modern design outlook. In addition, these smart watches apparently come with IP68 rating for dust and water-resistance.

As far as the Samsung Gear S2 specifications are concerned, the gadget flaunts a 1.2-inch fully circular Super AMOLED display, packed with a resolution of 360 x 360 pixels. This translates to a pixel density of 302 ppi. Under the hood, the smart watch comes powered by a 1 GHz dual-core CPU and backed by 512 MB of RAM.

When it comes to memory specification, the Gear S2 come equipped with 4 GB of built-in storage capacity. The device supports the following connectivity options: Wi-Fi: 802.11 b/g/n, Bluetooth v4.1 and NFC.

One of the variants of the device will reportedly support 3G connectivity along with e-SIM capability. This e-SIM will come with voice capability, which can be used to perform quick functions without interacting with the paired handset, according to Samsung.

Furthermore, there is a 250 mAh battery in the Gear 2, providing 2 to 3 days of normal usage, after a full-charge. However, the 3G model of the smartwatch will reportedly house a bigger 300 mAh battery with two days of battery life. The device also supports Wireless Charging capability.
